Kourtney first shared a photo of her getting in on the corset craze on January 30 with a picture of her in a black waist-trainer and the caption 'Gettin' it right, gettin' it tight...with my waist shaper!'

The mother-of three, who's married to Scott Disick, is the third Kardashian girl to try the corset approach and says she is 'on a mission' to regain her svelte shape.

Kim started the craze several months ago after raving about how the tightly-laced contraption helps her maintain her hour-glass figure.
